    installer: Fix mapper name generation for encrypted installation.
    
    fn_mapper_name() is supposed to take the mountpoint name, not the
    device name.
    
    This actually broke the install in environments where no /dev/serno/...
    device was available and both root and /build were selected for
    encrypting because the device name would never contain a '/' and so
    the mapper name 'root' was returned for both.
